Because the heating furnace belongs to a periodic operation mode, the lining body can be seriously damaged by extremely cold and hot temperature and excessive thermal oscillation in the operation process. The key operation temperature of each part (such as a furnace body and a slag weir) of the heating furnace is monitored in real time in the operation process, the corrosion condition of the lining body of the furnace is effectively analyzed, the control is carried out in advance, the economic and safe operation of the heating furnace is guaranteed, and the method has great significance. At present, the heating furnace is provided with 23 thermocouples for temperature online monitoring, but the thermocouples cannot correspond to actual devices in space positions, so that great difficulty exists in monitoring and maintenance.
In the prior art, a three-dimensional temperature field construction method (CN 112345084B) based on a digital twin environment includes acquiring data of a target point by using a scanning device, acquiring an infrared image of the target and a temperature value corresponding to each pixel point in the infrared image by using an infrared camera, wherein the positions of the scanning device and the infrared camera are relatively fixed; and for any view angle of the target object in the infrared camera, determining the position information of the scanning equipment according to the point cloud data of the target object and the pre-acquired environmental point cloud data, determining the position information of the infrared camera according to the position information of the scanning equipment, and determining the temperature value corresponding to the point cloud data of the target object by taking the position information of the infrared camera as a reference. The method comprises the steps of arranging a laser radar and an infrared camera on an unmanned aerial vehicle or a robot, moving the unmanned aerial vehicle or the robot around a target object by a preset route, and collecting target object point cloud data of each view angle of the target object, an infrared image and a temperature value corresponding to each pixel point in the infrared image. The method is only suitable for being applied to the target object in outdoor open scene, and cannot be applied to the heating furnace body in complex industrial scene.
A three-dimensional temperature field construction device, method and equipment (CN 111562029A) comprises the steps of controlling a signal transmission module to drive a plurality of ultrasonic sensor modules to circularly send control signals in sequence according to the space coordinates, and receiving feedback signals output by the signal transmission module to obtain sending time points of the control signals; obtaining a space temperature preset value by combining the sending time point, the receiving time point and the space coordinate with a space temperature analysis method; obtaining a space temperature value by combining the space temperature preset value with a normal distribution denoising method; and obtaining a three-dimensional temperature field model by combining the space temperature value with a three-dimensional temperature field reconstruction method. According to the invention, the temperature of the target space region is detected by the ultrasonic sensor, the ultrasonic sensor is used for measuring the temperature in the cavity of the furnace body, and the temperature measuring equipment cannot be installed in the heating furnace body in a complex industrial scene, so that the ultrasonic sensor cannot be applied to the heating furnace body in the complex industrial scene.
A blast furnace tuyere raceway three-dimensional temperature field construction method (CN 113343440A) based on image data comprises the steps of establishing a tuyere raceway three-dimensional temperature field model by using image data, firstly obtaining image information in a blast furnace tuyere raceway, and dividing an image into image pixel units; then, dividing the rotary area of the blast furnace tuyere, and dividing the rotary area into N cubic volume units; then calculating the space distance between each cubic volume unit of the convolution region and the image pixel unit; simulating the relation between the energy transfer of pixel points on the corresponding image and the space distance of the cubic volume unit of the convolution region through a Gaussian function, and further determining the relation between the radiant energy and the temperature through the blackbody radiation law; calculating the relation coefficient between the radiant energy and the image gray value through the temperature and the image data measured by the temperature measuring camera; and the construction of the three-dimensional temperature field of the convolution area of the blast furnace tuyere is realized. The invention utilizes the temperature measuring camera fixedly arranged in front of the blast furnace tuyere to acquire image information and calculate temperature data, and various heating furnaces (such as an Osmant furnace) in a copper smelting workshop do not have similar mounting hole sites, cannot be provided with similar temperature measuring cameras, and can only monitor the temperature of the furnace body through a contact thermocouple or a non-contact infrared camera arranged on the furnace body, so the invention can only be applied to a rotary area of the blast furnace tuyere.
A blast furnace wall three-dimensional temperature field reconstruction method and a computer monitoring system (CN 103614498B) comprise the steps of collecting the temperature of temperature measuring points on the furnace walls of a bottom section, a hearth section and a belly section of a blast furnace, carrying out data cleaning and data completion preprocessing on the collected temperature data, utilizing the preprocessed temperature data, adopting periodic cubic spline interpolation on the cross section of the furnace wall, adopting natural cubic spline interpolation to establish temperature distribution models on two surfaces, namely a furnace wall refractory brick center and an outer side cooling wall center, in the axial direction of the furnace wall from bottom to top, and finally adopting linear interpolation to establish a whole blast furnace wall three-dimensional temperature field distribution model between the two surfaces, namely the inner side refractory brick center and the outer side cooling wall center, and adopting OpenGL to display the temperature distribution state of the blast furnace in real time. The invention can only solve the problems that the temperature measuring point data of the blast furnace wall is abnormal, the temperature measuring point data are mutually isolated, and the overall temperature distribution is not visual. The invention can not solve the problem that no temperature thermocouple provides temperature measurement point data for slag weirs of various heating furnaces (such as an Osmant furnace) in a copper smelting workshop.

Wherein, the Osmant furnace is one of heating furnaces, and is called the Otto furnace for short. The slag weir is a structure used for pouring slag on the heating furnace. The overall design is a three-layer framework of a data source layer, a data service layer and an application layer. The data source layer is responsible for acquiring basic support data for the platform.

The embodiment of the invention provides an on-line furnace temperature monitoring platform, the structure of which is shown in figure 1, and the platform comprises: a data source layer, a data service layer and an application layer;
the data source layer is used for acquiring basic supporting data for the platform; the basic support data comprises furnace body temperature data; optionally, the data source layer is accessed to the DCS system, the PI database system, and the PLC control system to perform data transmission, and provide other interfaces of the information system. A Distributed Control System (DCS) is a new-generation instrument Control System based on a microprocessor and adopting a design principle of decentralized Control function, centralized display operation, and consideration of both autonomous and comprehensive coordination. The pi (plant Information system) is a commercial software application platform based on a client/server structure, and is used for automatic collection, storage, monitoring and the like of factory data. Plc (programmable Logic controller), which refers to a programmable Logic controller, is a digital operation electronic system designed specifically for application in industrial environment. It uses a programmable memory, in which the instructions for implementing logical operation, sequence control, timing, counting and arithmetic operation are stored, and utilizes digital or analog input and output to control various mechanical equipments or production processes.
The heating furnace is in a relatively closed environment in a complex industrial scene, such as a workshop or a workshop for installing the heating furnace, the environment comprises various pipelines and equipment besides the heating furnace, the space is limited, and dust and heat radiation in the air are high, so that the heating furnace is not suitable for moving around a target object by an unmanned aerial vehicle or a robot in a preset route to acquire point cloud data of the target object at each view angle, an infrared image and a temperature value corresponding to each pixel point in the infrared image. Various heating furnaces (such as an Osmant furnace) in a smelting workshop are not provided with mounting hole sites for temperature measuring cameras, so that the temperature measuring cameras cannot be mounted, and the temperature of the furnace body can only be monitored by contact thermocouples or non-contact infrared cameras mounted on the furnace body.
Specifically, the furnace body temperature data comprises position data of the surface of a furnace body slag weir and temperature data of a corresponding position, and also comprises temperature data and corresponding position data of other positions of the furnace body outside the slag weir, the temperature data and the position data of other positions of the furnace body are determined by the arrangement position of a thermocouple and the temperature data returned by a thermocouple sensor arranged on the furnace body, and the position data of the surface of the furnace body slag weir and the temperature data of the corresponding position are measured by an infrared imaging thermodetector because the thermocouple cannot be arranged on the surface of the slag weir. As shown in fig. 2, fig. 2 is a horizontal sectional top view of the furnace body, and at least one infrared imaging temperature measuring instrument is respectively installed on two sides of each slag weir of the furnace body. Furthermore, two infrared imaging thermometers corresponding to the slag weir are installed on the same horizontal plane which is not lower than the height of the middle position of the slag weir in the vertical direction, and the included angle formed by the two ends of the surface of the corresponding slag weir in the measuring range of the infrared imaging thermometers on the horizontal plane of the infrared imaging thermometers and the connecting line of the infrared imaging thermometers is not less than a first preset angle and not higher than a second preset angle. Other angles can cause the resolution ratio of infrared imaging to be too large or too small, thereby causing temperature measurement indicating value errors and influencing temperature measurement precision.
